. shaft is'provided with the sprocket 13 and means for conveying and handling the ./molds and brick being hereinafter fully set forth.

All parts of the off-bearing machine herein d'scribed are mounted upon the frame 'or connected to the base plates 3, 4 and 5 arranged upon and fastened to a level foundationin their appropriate relation to each other as shown in the drawings. The main m shaft 6 is rotatably mounted within the bearings T and 8 upon the base 3 and the bearing 9 on the base 4. The main shaft 6 is prOvided with the main driving sprocket 0/ which is connected to the sprocket 11 by means of the drivsupplementary counterthe sprockets 13 and 11 are each provided with a gear meshing with the gear on the 20 other sprocket to produce simultaneous rotation of the said two sprockets. .In elevated bearings 14 and 15 the rotatable shaft 6 ismounted and fixedly arranged upon said shaft is the sprocket 17, which is con- 25 nected'to the sprocket 13-upon the supplementary counter-shaft by the driving chain 18. It will thus be obvious that rotation of the sprocket 11 will produce rotation of the rocket 13 and that the shaft 6 and the s 3 siiaft 16 will be driven simultaneously and harmon with each other by reason of the care connection between the said sproc ets ll and 13. v Upon the base-plate 4.- is arranged the suport 19, which is provided with a vertical aring for the accommodation of the rotatable shaft 20. Upon the upper end of the shaft 20 is fixedly mounted the circular stroking ofi' knife 21, the flat, hollow, frusto- 0 conical form of which will be understood from ,a reference to Fig. 3, which includes a cross section of said knife upon what may be termed a diametrieal plane. Upon the lower end of the shaft 20 is arranged the 45 beveled gear 22, meshing with the beveled gear 23, which is fixedly mounted upon "the shaftg24 journaled in a bearing on the support 19. The shaft 25 is rotatably mounted insuitable bearings upon the base 4 and 50 1s provided with the gear 26 meshing with the gear 27 upon the shaft 24. The gears 26 and 27 together constitute a single intermittent gear and a view of said gear is shown in Fig. 12. It will be obvious that 55 although the gear 26 is continuously in rotatiojih the rotation of the gear 27 will be intermittent.

-The main shaft 6 is provided at its extreme end with the beveled gear 28, meshing 60 with the beveled gear 29, upon the shaft 25,'the shaft25 being thus driven by the shaft. 6. The table 30 is arranged under the circular stroking oil' knife and the upper surface of said table is slightly lower 06 than the upper surface of the, table 2 ofthe fingers 39 shafts 54 and 50 brick machine for the purpose hereinafter disclosed. Upon the sup ort 31in arranged a hearing within whic the shaft 821s journaled. Mounted u on said shaft '32 i8 the sprocket 33,-and at'the opposite end of 70 the gar34 meshing with the gear 35 upon w the'shaft25. An elevation of the gears 34 and 35 is shown in El 13, from which it will be obvious that afthough the gear 35 is continuously rotated the gear '34 will 75 only be intermittently driven by the gear 35, causing an intermittent rotation of the sprocket 33 for the urpose hereinaftermore fully disclosed. The idler pulleys 36 and 37 are suitably journaled to extensions of the table Y30 and a conveyer chain 38, is located over said idlers along the top of .the table 30 in a slot or depression in the surface of said table, and over a portion ofthe sprocket 33 as illustrated in Fig. 7. The at 0 adjustable which may be attached to .one of the links of said chain and are adapted to engage the mold for the' purpose of remov-' ing the same from the table 30 by sliding it ain 38 is provided with the longitudinally onto the rapping table which may be formed integrally with the table as shown in Fi 7 if so desired.- In the 'rapping table 40 t e transverse slots 41 and ciprocating movement of the upper ends of the pushing levers 43-43. These levers ex-f tend through slotted openings in the base plate 3 and are pivoted at points 44,-t0 downward extensions 45 of the base plate 3." At the points 4H6 the pitmen 4747 are pushing levers 43-43, and the said pitmen are connected by the wrist pins 48-48 to the cranks 49--49 fixedly mounted upon the shaft 50. The shaft 50 is rotatablymounted in the bear ings 51-51 and the ear 52 is-- fixedly mounted upon said sha tintermediate said bearings. On the shaft 50 are also mounted the sprockets 53-53 which are provided for the purpose hereinafter disclosed. Upon the rotatable shaft 54 journaled in suitable bearings isfixedly mounted the gear 55 meshing with the gear 52, the form of said gears being such as to produce a single intermittent gear connection between the as will be more fully dis closed by a referenceto Fig. 2, the arrange" ment of-the said gears being such that contin'uo'us rotation of the gear 55 will produce continuous rotation of the gear 52 and the shaftolfupon which said gear is mounted. The sprocket 56 is fixedly'mounted upon the shaft 54 and the sprocket 57 is fixedly mounted upon the shaft 6 and the chain-58 operatively' connects said sprockets andtransmits power from the main shaft 6 to the shaft .54 and the shaft 50 geared thereto. It is obvious that continuous rotation of the shaft-6 will produce continuous rotation of 1.0 I

42 areprovided to permit the rememos 0 gears and 52 I rotation of the ng with it the sprockets ranks lQ -elil. Rotation of 31st: oi-i9 will produce reciprocating movement "5 the pushing levers 45-43 by reason ot the connecting pitmen, the said pushing levers moving upon their pivotal points At the top end of the pushing levers are arranged the mold engaging flanges which are adapted to engage side of the mold and push the same across the table -10 into a position where it may be acted by the rapping hammers -6C2 The spaced brackets 61-451 are a hed in pairs to the lower side of the ts $0 and upon ins, 6262, ex tending between the two brackets of each pair the lever portions of the rapping hammers are pivoted. The lower ends of the said lever portions 63 extend to the main shaft 6 where they are engaged by the cams (ii-6% adapted to give reciprocating motion to the lower ends of the said lever portions thus rocking the rapping hammers upon the pivotal points 62. To aid in the operation of said hammers the springs 65 are pro vided one end of each spring being fastened to the lever portion 63 at a point above the -votal. point 62 and the other end being fa cued to-the underside of the rapping t2 hie so as illustrated in Fig. 7. It is obvious that the continuous rotation of the main shaft 6 will produce a rapping action on the part of the hammers 60 and that when the mold has been pushed by the levers 43- 23 into a. position between the rapping hampers the said hammers will engage the ends of said mold and rap the same for purpose of loosening the bricks therein.' The mold will remain upon therapping table and will be continuously rapped by the hammers 60 until a new mold has been moved onto the t ble 4:0 by the operation of the conveyer cu n 38 and the fingcrs 39 and until the pusuing levels 43 have pushed the second mold into the position previously occupied by the first mold between the rapp'ng hammers thus pushing or crowding the mold which has been rapped oil? of the rapping table and onto the rotatable reciprocating dumping cradle 66, the construction and operation of which are now to be described.

Upon the base 5 are erected the supports 6? having arranged upon their upper ends the cradle ways 68 forming longitudinal grooves on each side of the machine and thus providing a slot or track within which the bearing bloc 69 are adapted to be arranged for l 'itudinal slidingmovement. The cradle HILL, '70 upon which the cradle 66 is fixedly mounted is rotatably iournaled in hearings in the said bearing blocks 69 shaft 16 in the elevated bearings M and 15 and the means for rotating the shaft 16 by the chain 18 he ve been heretofore described.

Beyond the bearings 1% and 15 and upon the shaft 16 are fixedly mounted the cranks '74 and respectively, which two cranks are of the same length. The pitman 71 is pivot ally connected to the wrist pin 76 on the crank 75 and the pitman 7 3 is pivotally con nected to the wrist pin 77 on the crank 74.

Fixedl'y attached stud 78 upon which is rotatably mounted the sprocket 79 and gear 80, said sprocket and gear other and the stud 78. By a reference to Fig. 5 it will be seen that the teeth in the gear 72 are broken away at two places, and the gear 80 is provided withteeth for only a ortion of its circumference; it will be obvious from to the pitman 73 is a.

being fixedly attached -to each' adapted to rotate togetherupon havthis that one complete rotation of the gear:

81 will rotate with the crank 74 with the rotation of the shaft 16, but that no rotation will take place as between the sprocket 81 and the said crank 74. The sprocket 79 and the sprocket 81 are connected by the chain belt 82. It will be obvious that rotation of the shaft 16 will produce rotation of the cranks 74, carrying with them the pitman thereto. the bearing blocks 69 sliding longitudinally within the cradle ways 68. It should also be noted that during rotation of the crank 74 the sprocket 81'being con- 11G 71 and 73 and dumping cradle 66 attached nected. thereto will make one revolution with respect to the sprocket 79 and that the chain belt 82 extending between said sprockets will produce one complete revolution of the sprocket 79 for each rotation of the crank 74. From the previous description of the relation of the gears 72 and 80 it will be readily'apparent that one complete rotation of the crank 74; will'not only produce reciprocating movement of the cradle within the wavs 68 but will also produce one-half revolution of said cradle itself.

The relative posi tions of the cars 72 -and 80 illustrated, in Fig. 5 is the position which 16 revolved, I describing the said gears occupy with reference to each other at the time When the cranks 74 and 75 arein their most rearward direction as illustrated inFigs. 1 and 2. It will be evident therefore that the said cranks 74 and 75 will continue to rotate for a short distance before the teeth in the gear .80 are brought to mesh with the teeth in the gear 72. Because of this fact the cradle 66 will move in the ways 68 for a short distance illustrated in dotted lines at 83 of Fig. 2 before the said cradle begins to revolve. When the cradle has reached the point 83, however, the gears 80 and 72begin to mesh and the cradle is curve illustrated in dotted lines at 84 in Fig. 2 until the point 85 is reached. This point 85 is reached before the cranks 74 and half revolution, and the gears 72 and 80 being now. no longer in mesh the cradle will remain at rest in so far as rotation is concerned, and While the'cranks 74 and 75 proceed in their rotation to the point diametrically opposite'that illustrated in Figs. 1 and 2 the-cradle will be moved in a straight line 1 illustrated by the dotted lines between the in Figs. 1 and 2 the gears 80 and 72, still remaining out of mesh,

thecradle 66 Willcontinue without rotation until the cranks 74 and 75 assume a point in their rotation slightly beyond the point lliustrated in Figs. 1 and 2 when :another half revolution of the cradle'will take place in the same manner as that just described.

In the drawings 87- 87 represent molds containing bricks, while 88-88 indicate empty molds. Each mold is formed with bottom,o ends and sides partitions to form' the individual brick A lon 'tun of one of said molds is ilusit Will be noted that athc bottom projects slightly beyond each .{cnd of the mold producing the flanges 89 ,It'or the purpose hereinafter set forth.

While the mold is yet upon the rapping table and just previous to its being pushed by the pushing levers 43 onto the upturned cradle bottom an attendant standing by should place a pallet or board upon and across the top of the mold, said board or pallet being exactly, as Wide and as long as the mold proper not including the flanges 89. Said pallet is intended to lie loosely upoili the top of the mold and is not fastened to. t When the pushing levers 43 bring a new mold into engagement with the mold just rapped and ush the said rapped mold onto the upturne cradle bottom the pallet is carsliding upon the cradle bottom between the end flanges 92 into the position illustrated in Fig. 2. Through each end flange 92 ex tends a slot, 94. The bottom of said slot is elevated from the surface of the cradle bottom 2. distance equal to or slightly greater than the thickness of the bottom of one of the molds, or in other words a tothe hickness of the flange 89. Pivotally arran" ed upon the pin 95st the under side of each cradle bottom is the lever 96 to which is pivotallv each ing link is in turn pivoted to one end'of the slidingly adjustable mold engaging device and upon the outside of flange 92, and is again bent at, right angles to enter the slot 94 and extend through'the same and beyond the inner surface of said flange as shown at 99 in'Figs. 4 and 5. The portion of the mold engaging device which thus extends through tl e slot 94: and beyond the inner surface of the flange 92may be called the mold engaging finger or more properly speaking the flange-engaging fin- 10 same while on the rapping table.v

It will be understood that the lever 96 be moved upon the pin 95 as its pivotal point the mold-engaging device will be unoved longitudinall and the flange engaging fingers will be drawn back and out of engagement with the flanges 89. For the purpose of normally holding the lever 96 in such position as to cause the flange cn- ,tuagiliglingers to engage the flanges of the molds the spring 100 is provided, wh ch spring is fastened to the under side of the ind piece during *she said revomovement of the cradle. a bed, the cradle. makes on as: advances forward, as

shaft 122 is rotatably mounted and upon 'ets said'shaft are fixedly arranged the s roc 123-123. The chains 119 extend mm the sprockets 120 to the sprockets 123 providing the chains an endless conveyor upon which the pallet with the bricks, when lowered by the arms 112 may be carried out and away from the machine. For the purpose of rotating the shaft 122 and eonveyin said bricks .upon 119 the pu ley 124 is fixedly mounted upon the shaft 122 and a twisted belt 125, connects said pulley'124 with the pulley 126 upon the shaft 16. The shaft 16 being in continuous rotation, .it will be understood that the shaft 122 will be in continuous rotation and that the pallet with the bricks thereon will thus be carried by the conveyor chains 119 to the edge of the machine where they will be deposited upon the pallet-receiving rails 127-127 from which point they may be carried by workmen or may be further convtiyed by power to the dry kiln as desired.

t the time when the pallet-retaining devices are shifted and permit the pallet and bricks to drop from the cradle the flange-cngagingfingcrs 99 remain unmoved and retain the empty mold in its position in thecradle until the said cradle has reacheditsextreme rearward position shown in vFig. 2. As the cradle nears the extreme rearward position the trip 101, heretofore described engages one end of the le- 1 ver 96 on. the lower cradle bottom, as illustrated in Fig. 5 in dotted lines, and by the continued motion of the said cradle into its said extreme rearward position, the said trip causes the said lever to be moved on its pivotal point, thus actuating the various parts connected therewith asherctofore described, withdrawing the flange-engaging fingers from engagement with the flanges 89 upon thev two ends of the mold and permitting the said mold to drop from the cradle onto the sanding barrel hereinafter described. It should be stated that at the same time that the trip 101 engages the'lever 96 two other trips, 128128 engage the projections 111 on the arms 102, thus shifting the pallet-' retaining devices by moving the said arms upon their pivotal points in the opposite direction from that heretofore described in connection with the trips 118, but bringing the pallet-retaining plates 106 instantly closer to the flanges 92 as before described in connection with the said trips 118, and thus permitting the mold to freely drop fingers 99 are actuated the pivoted pawl 138 is said' ratchet cam, permitting the barrel 130 thus assured.

the flange-engaging to release said mold. In Fig. 2 the'mold is illustrated as having just dropped into place upon the sanding barrel and the construction and'operation of the sanding barrel in connection [with the molds is now to be described. In upon extensions of the base plate 3 is journaled the barrel shaft 129 to which is keyed and firmly attached the barrel 130 having two. diametrically opposite openings in its 7 sides, one of said openings being shown turned upwardly and the other op'eiiing' downwardly in Fig. 8. The barrel is=provided with a flat head at each end having an. 30 integral boss or hub located on the shaft129 v and keyed or fastened thereto; At one-fend the shaft 129 is extended through 'the'bearing and upon it is fixedly mounted'the sprocket 131. Upon the main shaftlfi is from the cradle when fixedly mounted the gear 132 provided with] v 1 a short shaft having fixedly mounted there on the gear 134 and the sprock t 135, h '3 gear 134 is provided at two places uponits circumference with teeth and initwo other 1 places upon its circumference the teeth are. broken away. The gears 132 and 134 are adapted to mesh gethcr constitute a double intermittent gear; so that continuous rotation of the shaft6 with the sprocket 132 will produce intermittent rotation of the gear 134 and the sprocket 135 mounted upon the same shaft therewith, one completerotation of the gear 132 producing one half-revolution of'the gear 134, and the gear 134 remaining at rest] while the gear 132 is performing the greater part of its rotation. The movements .Qfthe H gear 134 and the sprocket 135 connected 7 therewith are transmitted to thesprocket 131 and the sanding. barrel 130 connected therewith by means of the chain belt 136.v At the opposite end of the shaft 129 from that on which the sproiikct 131 .is'mounted the ratchet cam 137 is fixedly mounted and adapted to=engage torevolve in its appropriate direction, but upon the completion of each half-revolution of said barrel preventing any backward rotation which the said barrelmay have a tendency to'make by reason of the over weight of sand-in said barrel as shown in Fig. 2 or for other reasons. A positive halfrevolution and a positive period of'rest is Within each opening in the sides of the barrel 130-is arranged flange 139, which flange extends along the sides of said opening as well as across the endsof the same and'zs attached to the sides and'ends of the barrel proper. g n an bearings V Upon the base Plate 3 is crected'jth 1" I bearing 133 and in said bearing. i journaled .95 f I with each other and to themold-supporting I mechanism or greases of the barrel is provided with the same one of said openings will alone be consldered. Along one side of the opening'and beyond the flange 139 is located the moldthrowing shaft 140, whichextends from end to end of the barrel and is journaled in appropriate bearings. at each of said ends. Upon one end of the shaft 140 is arranged the cam lever 141 which is'fixedly mounted upon said'shaft and is adapted to engage the trip 142, which is fixedly attached ;to..the base 3 as shown in Fig. 8. As the barrel 130 is rotated and just before'the openin has reached its uppermost position the sai cam lever 141 engages the said trip 142 and gives to the shaft 140 a,twist or partial rotation. Fixedly mounted upon the shaft 140 are the mold-throwing fingers 143143 which extend across the opening of the sanding barrel and lie in depressions in the flange 139, thus bringing their upper surfaces in a plane with the upper surface of the said flange. The said fingers are provided with of the barrel 130.

projections or stops 144 for the purpose hereinafter described. For the purpose of returning the shaft 140 to its normal position with the pressions in provided, which spring is attached to the shaft 140, is wound has its other end attached to-the wall of the barrel 130. At the time when the mold drops from the dumping cradle 66 onto the sanding barrel the sanding barrel and its parts are in the'position shown in Fig: 8, the cam lever 141 having already passed the trip 142 and the fingers 143being in place so that the mold may drop upon the flange 139. The mold having been, dropped upon the flange 139 is held agaihst lateral displacement by the stops 144 and the flange 146, the same being an extension of the side The ends of the barrel areextended into the end flanges 147--147, which prevent longitudinal displacement of the mold. For, the purpose of holding the mold in placeagainst the flange 139 and preventing it from 'dropping out of engage ment with said flange during the rotation of the barrel, the mold-retaining fingers 148- 148 are provided. Each of these fingers is fixed upon a short shaft 149 journaled in appropriate bearings arranged upon the head of the barrel. Intermediate the said bearings the spring 150 is provided. Said spring is attached at one end to the shaft 149, is wound about said shaft, and has its other end attached to the head of the barrel in such way that the action of the said spring normally holds the mold-retaining finger 1-18 extended longitudinally of the barrel and inwardly, or in other words over the bottom of the mold, the said finger being located at a suificient distance from devices and for this reason bearings and fingers 143 lying in the de-' the flange 139 the spring is about said shaft, andmold as is preferably of the form illustrated in Fig.

8. The said cam lever and stop is provided with an integral portion 152 adapted to engage the end of the barrel and limit the action of the spring 150, thus causing the said: spring to hold the finger 14S normally in the position to engage the bottom of the mold, as described. Another integral portion 153, is adapted to engage the trip 154 for the purpose of rotating the shaft 149 within its throwing the finger 148 out of engagement-with the bottom of the mold and into a position practically in line with the plane of the end of the barrel. The said trip 154 is preferably of the form illus. trated in Fig. 8 and has a curved or beveled portion adapted for engagement with the portion 153 of the cam lever stop and is adapted to give the said portion sufficient throw to disengage the linger. 1481 from the bottom of the mold as scribed. I

For the purpose of jarring the mold to disengage any undue amount of sand which may stick to it aftcrhaving been revolved with'the sanding barrel :oeclianism .is provided, which niechanis 2. is adapted to jar the said mold as the he approaches the position shown in Fig. 8 just previous to the throwing over of the hereinafter described. The knocking mechanism consists of a lever which lever is provided at its lower end with the right angled integral 0x 1" its upper end with tho hrs or ti0n157. At the point 158 is pivotally attached to .11 rel and at the point 1 39 attached to the lever 135, the other, endo'i said-spring being attached to :l for the purpose of bring I 1 head I into engagement with the e d o" the mold.

I g more. In 50 csnnectm ionglluanna JLO dumping cradle, which is'at that instant in a the position shown in Fig. 2. Just before the mold is pushed onto said dumping cradle the pallet 203 should be placed upon the top of the mold by an attendant as hereinbefore described'and the said pallet will enter the said dumping cradle with the mold. At the timewhe'n the mold .with the pallet thereon is thus pushed onto the dumping cradle the flange-engaging fingers and the pallet-engaging plate and related devices are in the position illustrated in Fig. 5. The continued rotationgof the shaft 16, which revolves at all times at a uniform speed, will cause the .pitmen 71 and 73 to draw forward the dumping cradle and the sprockets 81' and 79 and the gears 80 and 72 will cause the one half-rotation of the dumping cradle while it is moved forward. the corner of the dumping cradle from which the dotted lin e 84: in Fig. 2 proceeds describing the path illustrated by the said dotted line 84.

When' the dumping cradle with the mold reversed by reason of the one half-rotation just described has reached its most forward position'the trips 118 will engage the pro JGOtlOIlS 111 on the pivoted arms 102, thus removing the pallet engagifigplates 106 from their engagement with the pallet, as

posited upon the cross heads of the arms 112 which act to permit the said pallet and 'bricks to descend slowly and without jarring onto the conveyer chains 119. The said.

chains being in continuous rotation, the said pallet and bricks will be carried out .to the end of the machine and onto the pallet re ceiving rails 127127 while the further rm inold therefrom while the trips 128 will- I actuate the pivotedv arms 102 to throw the pallet engaging plate 106 nearer theflanges 92 to permit the said mold to drop freely into place upon the sanding barrel. At the time'the said mold drops upon the said sanding barrel the said sanding barrel is in the position illustrated in Fig. 8 and by the filrther rotation of themain' shaft 6 the .gears 132 and 134 are thrown into mesh and the revolution of the sanding barrel is commenced. The said revolution progresses but a short space when the mold retaining fingers 148 are thrown into engagement with .the bottom of the mold and remain in such engagement until the said mold is brought hereinbefore described,'an'd permitting the. said pallet with the bricks thereon to be deagain nearly to its top or upward position as hereinbeforc fully described. As the said mold is brought to the top position-it is rc-. leased from said barrel and thrown by the mold throwing fingers 143 onto the inclined conveyer consisting of the chains 165. The

sanding barrel will-then remain at rest until it receives another mold to be sanded, while the chains 165' will be put into motion by the operation of the intermittent gear composed of the gears 52 and 55 and the sanded mold will be conveyed upwardly as shown in Fig.

until it has reached the mold receiving moving parts of theen'tire machine is such that each device will operate at th'eproper instant and that the various parts will oooperate with each other to perform their necessary functions in as speedy a manner as possible. .The brickmaking machine will be intermittently feeding re-filled molds into the off-bearing machine and the said off-bearing machine 'will so operate as to take care of the various molds as fast as are fed into it, a series of molds being'thus continuously entering the machine, a series of pallets and bricks being delivered onto the pallet-receiving rails and the molds from which said bricks have been taken being sanded and returned to the brickmaking machine in a similar series, all of. the various operations belngperformed m amore or less intermittent manner as will be fully understood from the above complete descri tion. It will'thus e seen that the ofl"-bearin machine for brickmaking herein describe is admirably. adapted to accomplish the i work for which it is designed and that all of the objects and purposes of the invention have been fully attained.
